5.6 Titrations and pH curves


Titrations are often used to analyse the amount of acid and base in a solution. The principle is to
continuously add a solution with known concentration to the solution with unknown concentration. The
addition is done from a burette in such way that the amount of added volume may be written off afterwards.
The point of equivalence is often signalised by a color shift from an indicator added prior to the titration. The
process of titration is often depicted by plotting the pH of the unknown solution as a function of the added
amount of solution with the known concentration. Calculations of pH for given amounts of solution with the
known concentration is done analogously to pH calculations exemplified in earlier sections.
